I installed my underdrive pulley now it seems the battery wants to die on me! I have an 00 GT 5speed and i only installed the water pulley and the crank pulley! I didnt install the alternator pulley because it was to hard (no impact wrench) and they look indentical! Ok now the problem I drove fine today for about 3 stops then when i get to crank it up it cranks 1 time then everything just dies! I need to get jumped then about 4 arons later it wont start up! Its weird because no battery light comes on while im driving it drives just fine! Seems like when i let it sit i try to crank it up and it wont crank! Now do i need a smaller belt? The stock one seems a little loose with the new setup! the alternator pulley is turning though but perhaps slipping?? Let me know please guys im new!
